Realization and Simulation of Fully Integrated MOSFETC Current Version Fourth Order Low Pass Filter Using OPAMP

提出了基于运算放大器的电流模式ＭＯＳＦＥＴ－Ｃ全集成精确连续时间平衡结构四阶低通滤波器电路，并应用ＰＳＰＩＣＥ通用模拟电路程序，对其幅频特性和相频特性进行了计算机仿真分析，得出了实用的结论．

This paper proposes a precisely continuous time fourth order low pass filter with balanced structure based on an op amp and a fully integrated MOSFETC of current version.Using PSPICE, simulation and analysis of the characteristics of the output voltage amplitude frequency response and phase frequency response of the filter have been performed. Some practical conclusions are obtained.
